ROCKING-CHAIR.

SPECIFICATION formingpart of Letters Patent N0. 242,442, dated June '7,1881. Application filed August 30, 1880. (No model.)

To all whom it may concern Be it known that I, PETER FELDEN, of Ohicago,in the county of (look and State of lllinois, have invented a certainnew and useful Improvement in Rocking-Chairs, of which the following isa specification.

The object I have in view is to produce strong, durable, noiseless, andsimple springconnections for platform rocking-chairs which will notinterfere with the bottom of the seat nor with the cross-rails of theplatform, and will hold the chair firmly upon the platform and confineits rocking movement within safe limits, and will prevent both lateraland longitudinal slipping of the rockers on the baserails without theuse of stops or guides, and will at the same time give an exceedinglyeasy movement to the chair-body.

My invention consists in the peculiar con-' struction of the springs andthe means for attaching them to the rockers and side rails of theplatform, as fully hereinafter explained, and pointed out by the claims.

In the accompanying drawings, forming a part hereof, Figure 1 is anelevation, of the inside of one of the rockers of the body and one ofthe side rails of the platform or base with my improved spring-connection attached thereto. Fig. 2 is a top view of the spring, andFig. 3 a cross-section through one of the bracketirons and one side ofthe spring on line 3 3.

Like letters denote corresponding parts in all three figures.

A is one of the side rails of the platform or base, and 13 thecorresponding rocker of the body of a platform rocking-chair, suchrocker restingdirectly upon said side rail.

01s a continuous plate-metal spring, theupper and lower sides of which,at thecenter, are

secured, preferably, by rivets to the horizontal wings a of cast-metalbracket-iron D D. The vertical wings I) of these bracket-irons havecountersunk holes, through which wood-screws are turned for securing thebracket-irons to the rocker and base-rail. ()11 each side of thebracket-irons the two parts of the continuous plate-spring are benttoward each other, as shown at o, and are then spread apart, and formrounded loops (1. These loops d project considerably more below theupper surface of the inner side thereof is spread apart somewhat, so asto draw them firmly together. The spring, while allowing a free and easyrocking movement within safe limits, has great lateral stiffness,preventing any lateral displacement of the chair-body on the platform.The spring also, by being continuous, and by reason of extending 011both sides of the bracket-irons, prevents the rocker from slippinglongitudinally on the side rail of the platform, since one part of thespring counteracts the tendency of the other part to effect such aslipping movement in rocking. If the spring were made ahalf-spring-thatis, were extended only on one side of thebracket-irons-it would cause the rocker to slip longitudinally on thebase-rail in rocking, and would therefore make a noise. The continuousspring can also be made of lighter steel-plate and cheaper than thehalfspring, and,by extending on both sides of the I bracket-irons, itneed not project so close to the front cross-rail of the platform.

It will be understood that two of my springconnections are used on eachchair, one being secured to the inner side of each rocker of the bodyand the corresponding side rail of the platform or base.

I wish it understood that I do not claim as any part of my invention thehalf-spring for this purpose, some of the disadvantages of which havejust been set forth.

' What I claim as my invention is 1. In a platform rocking-chair, thecombination, with the base-rail A and the rocker B, resting directlyupon the base-rail, of the bracket-irons D D, secured rigidly to saidrocker and base-rail at or near their center, and the continuous doubleplate spring 0, bent from a extending on both sides thereof parallel tothe single piece of metal and secured rigidly at its center to saidbracketirons, such spring extending on both sides of the braekctironsparallel with the rocker and base-rail, and having free ends,substantially as described and shown, for the purpose set forth.

2. In a platform rockin g-chair, the combination, with the base-rail Aand rocker B, of the bracketirons D D and the continuous platespring 0,secured to such bracket-irons and basc rail and rocker, said spring;being bent inwardly at c and outwardly to form rounded loops (1 at itsends, which loops extend more below than above the top of the base-rail,substantially as described and shown.
